How can firefighters protect themselves against exposure to airborne pathogens?

Using a self-contained breathing apparatus (SCBA) is essential for firefighters to protect themselves against airborne pathogens. SCBAs provide respiratory protection by supplying clean, compressed air to the firefighter, effectively creating a barrier between the inhaled air and any potentially harmful contaminants present in the environment. This is particularly critical in situations where smoke, chemicals, or infectious materials may be airborne, as these can pose serious health risks.

While wearing gloves is important for physical protection and can help in preventing other types of contamination, it does not protect against inhalation of pathogens. Similarly, applying ointment and taking medication would not be effective preventive measures against airborne pathogens, as these do not address the respiratory exposure. SCBAs are specifically designed to ensure that firefighters can breathe safely in hazardous environments, making it the most effective option in this scenario.
